Zaha Hadid Arhitects has created a chamber music hall for solo performances of Johann Sebastian Bach's chamber music masterpieces. Their latest project for the Manchester International Festival. The form, a suspended ribbon of translucent lightweight synthetic fabric articulated by an internal steel structure, translates the intricate relationships of Bach's harmonies into an architectural spatial condition. Unique specialy designed to enhance the multiplicity of his music by using a single, continuous ribbon of fabric which continuously changes, stretces, compresses and moves around itself to cocoon both performers and audience within an intimate fluid space. ZHA and Sandy Brown Associates worked together to perfect the acoustics using CAD models that were imported into acoustic modelling software that tested the different finishes and shapes of the curving form.
